Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...

Aqueous electrochemical energy storage devices have attracted significant attention owing to their high safety, low cost and environmental friendliness. However, their applications have been limited by a narrow potential window (∼1.23 V), beyond which the hydrogen and oxygen evolution reactions occur. Here we report the formation of layered Mn5O8 pseudocapacitor electrode material with a well-o...

A heterogenous catalyst in the form of Au nanoparticles (Au NPs) immobilized porous manganese oxide (Mn5O8) microspheres was synthesized. The sol-gel templating method used for synthesis Mn5O8 microspheres. showed good performance when compared with similar catalysts oxidation benzyl alcohol. (Au@Mn5O8) obtained by immobilization NPs on performed 99.4% alcohol conversion and 100 % benzaldehyde ...

We have investigated the crystal, electronic, and magnetic structures of Mn5O8 by means of state-of-the-art density functional theory calculations and neutron powder diffraction (NPD) measurements. This compound stabilizes in the monoclinic structure with space group C2/m where the Mn ions are in the distorted octahedral and trigonal prismatic coordinations with oxygen atoms. The calculated str...

Manganese oxides are one of the most important groups of materials in energy storage science. In order to fully leverage their application potential, precise control of their properties such as particle size, surface area and Mn (x) (+) oxidation state is required. Here, Mn3O4 and Mn5O8 nanoparticles as well as mesoporous α-Mn2O3 particles were synthesized by calcination of Mn(II) glycolate nan...

tio2 nanorods can be used as dye-sensitized solar cells and as various sensors and photocatalysts. these nanorods are synthesized by a using thermal corrosion process in a naoh solution at 200 oc with tio2 powder as a source material. in the present work, the synthesis of tio2 nanorods in anatase, rutile and ti8o15 phases and the synthesis of tio2 nanorods by using the sol-gel method and alkali...

self-assembly of densely packed zno nanorods were grown on porous silicon (ps) substrate by low-temperature chemical bath deposition. the structural and optical properties of the obtained zno nanostructures on ps substrate were systematically studied. the strong and sharp (002) peak compared with other peaks in the x-ray diffraction (xrd) indicated thatzno nanorods formed with superior orientat...

in this study, the tio2 nanorods were synthesized from p25 tio2 nanoparticles by hydrothermal method in 10 m naoh solution. the effects of annealing temperatures on produced nanorods were investigated  by scanning  electron microscopy (sem) x-ray diffraction (xrd) and photoluminescence (pl) spectroscopy. diameter growth and  changes  of  surface  oxygen  defects of  synthesized nanorods are stu...

Hematite (α-Fe2O3) nanorods were synthesized by hydrothermal method using Cetyltrimethylammonium bromide (CTAB) as a surfactant agent. To study optical, nanostructural properties, and to control the morphology and shape of nanorods, 0.025 mol L-1, 0.05 mol L-1 and 0.1 mol L-1 concentration of CTAB were used. Moreover, the effect of interaction between bovine serum albumin (BSA) A9418-5G protein...
